LINOTYPE-MACHINE.

To all whom it may concern a it known thatyI, WILLIAM E. BERTRAM, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New .York, have invented new and useful Improvements in Linotype Machines, of

which the following is a specification.

The present invention relates to improvements in linotype machines and more especially to the trimming knives whereby the slugs are trimmed to uniform thickness and irregularities and imperfections are, re-

moved, and the primary object of thisin-' vention is to provide improved means for mounting and adjusting the relation between the knives whereby they may be quickly-and correctly'set and locked in different relative positions to trim slugs to different standard thicknesses.

Another object of this invention isto provide simple and improved means whereby the angular relation between the knives may be readily adjusted in order to maintain the knives in parallelism and thus compensate for sharpening an uneven wear of the knives, and to provide a corresponding compensating adjustment for the knife-setting means.

To these and other ends, the invention consists in certain improvements and combi nations and arrangements of parts, all as will be hereinafter more fully described, the

novel features being pointed out particularly in the. claims at the end of the speci fication. p

In the accompanying draw1ng:'Figi ire 1 is a perspective view oftheforward side i of the vise and the knife block of a linotype machine embodying the present invention; Fig. 2 is a rear elevation of the parts 1 shown in Fig. 1 Fig. 3 represents a hori- 51. knives, which operate to zontal section-on the linb 3-3 of Fig. 2 and looking in-the'direction of the arrows; Fig.-

Similar parts'are designated by the same reference characters in, the several views.

In, linotype machines of thetypes commonlyused, the cast slugs are ejected from the mold by an ejector blade which moves the slug edgewise, and this e ector blade forces the slugs between a pair of parallel trim the flat sides of Specification of Letters Patent.

different standard sizes of slugs which may be made in the machine, and simple means is also PlOYldBd, for relatively adjusting the knives in an angular direction in order'to compensate for unevenness due to sharpening or wear. .The means provided by the present invention for setting the knives for slugs of different standard sizes compensates for the relative angular adjustments be tweenthe knives.

' Tie accompanying drawing shows the preferred embodiment of the invention, but it will be understood that the invention is not limited to the precise details and the relative arrangement of the parts, as modifications or changes may be made in the practical application of the improvements to different machines.

In the present instance, the knife block 1 is shown attached to the vise 2 of themachine, and one of the knives, the knife 3 in the present instance, is rigidly secured in fixed position on the vise 2 and at one side of the'slot 4 through which the trimmed slugs discharge. The knifeblock at the opposite side of the slot fl is formed with an extenconnected thereto by a screw or sion 5 and a swivel plate or member 6 is apit being pivotally pivot 7 which is preferably arranged midwayof the length of the'knives. The pivotal connection between the swivel plate or member 6 and the knife block permits angular adjustments between these parts. Tofacilitate such adjustments, an adjusting screw 8 is provided, this screw being supported by an arm'9 wliich is attached to or forms partofthe extension 5 ofthe knife block-and he end of the screw bears against the adjacent side or edge of the plate or member 6, the screw operating in the plied to, this extension,

plane of this plate or member. In order to maintain the plate or member 6 in proper angular relation to the knife block, a screw or its equivalent 10 is employed, this screw in the present instance passing through an aperture 11 in the plate or member 6 and also through a slot 12in the arm 9, such slot being concentric with the screw 7 as an axis, and a nut 13 onthe screw 10 serves to clamp the plate or member 6 and the arm 9 firmly together, thereby preventing shifting of these parts after they have been set in proper angular relation.

The adjustable knife 141 is in the present instance attached to a knife holder 15, and

this adjustable knife and its holder are mounted and guided to move rectilinearly on the plate or member 6. In the present instance, the rear side of the knife 14 is formed with a dove-tailrib 16 which 0perates longitudinally between complemental guides 17 on .the adjacent face of the member 6.' To insure rectilinear movement between the knife and its holder and the. plate or member 6, the holder is preferably formed at its rear end with a rib 18 which operates in a longitudinal groove.19 in the plate or member 6. Movement of the knife 14: and its holder relatively tothe swivel plate or member 6 serves to vary the distance between the knives to correspond to slugs of the size to be trimmed. In practice, the various sizes of slugs are known by points and the points vary in size by fourteen thousandths of an inch. The present invention provides means whereby the relation or distance between the knives can be instantly set so as to operate properly upon slugs of any selected standard size and when so set, the knives are firmly locked in proper adjusted relation. The means shown in the present instance for accomplishlng these'results embodies a graduated bar or-member 20 which is provided with a series of apertures 21, these apertures being spaced longitudinally of the bar or member. and each of these apertures is located at a different distance from the operative edge of the adjustable knife 14:. llie difference in spacing of the, apertures 21 from the operativeedge of the adjustable knife preferably corresponds to 1 the difference between each point or standaid type size in which case the difference in spacing between any two ad acent apertures 21 with respect to the operative edge of the tures' 21 in the graduated member 20 to successively register with the apertures 22, a

different aperture 21 registering with a different aperture 22 for each movement of the adjustable knife to the extent of fourteen thousandths of an inch. The adjustable knife -may be retained in the different ad-' justed positions by a locking pin 23 which is capable of insertion into one of the apertures 22 and the registering aperture 21 in the graduated member. A scale 24, the indicating characters 'of which preferably correspond to the well known designations of the different points,.is preferably provided for the set of, apertures 22 in the member 6 whereby the locking pin 23 may be instantly inserted into the aperture 22 corresponding to the desired point, and when the adjust; able knife has been moved into a position where the correspondingaperture 21 in the graduated member 20 registers with the aperture '22 containing the locking pin, this pin maybe caused to enter the registering aperture'21 and'the adjustable knife is then properly set. V

Adjusting movements of the knife 14 may be accomplished by different means, that shown in the presentinstance embodying a handle 25 which is mounted to rock on a pivot 26 supported at the forward side of the knife block extension 5, and the opposite end of this handle has a fork 27 which cooperates with a transverse pin 28, the latter being supported by'lugs 29 on the knife hold; 12" After the knife 14: has been proper y adjustedand set, it may be clamped firmly to prevent alteration of its adjustment. In the present instance, a

screw 30 is provided the head of which bears on the knife holder 15 and the forward threaded end of this screw receives a clamping handle 31, the clamping handle bearing against the forward side of. the swivel plate or member 6, the latter being formed with an elongate'dslot 32 to permit the passage of the clamping screw 30 without interfering with the adjustment of the knife.

In order that the graduated bar or member 20 may be adjusted in accordance with angular' adjustments of the swivel plate or member 6 to compensate for sharpening er uneven wear ofthe knives, this bar or member is made separately from theknife holder v 15 and is seated in atrans'verse channel 33 which is formed in saidknife holder, the

opposite walls 34.- and 35 of said channel supporting screws 36 and 37, these screws being arranged in pairs-and operating upon the respective longitudinal edges of the graduated bar. In order that these screws may retain the graduated bar in proper po sition and prevent itsdisplacement from the channel, the respective'edges of. the'bar are beveled as at 38 and 39. Longitudinal movement of the graduated bar in the chair Lunar:

nel is prevented by a pair of shouldered screws 40 which extend through transverse slots 41 in the bar and are threaded into the apertures 42 in the bottom of the channel these screws, however, permitting the grad uated bar to be adjusted in a direction tograduated bar 20 is held in such position by the screws 36 and 37 that the registration of each of the apertures 21 in this bar with the corresponding aperture 22 will occur when the knives are spaced apart a distance equal to the thickness of a slug of a corresponding size, and when the apertures corresponding to the selected size have been brought into register, the locking pin 23 may be readily inserted to retain the knives in set position, it being possible for the operator to readjust the knives for the different size slugs quickly and with the greatest facility. Should the parallelism between the operative edges of the knives be destroyed owing to sharpening, wear, or other causes, the knives are again brought into parallelism by shifting the swivel plate or member 6 about the screw 7 p as a center until-the edges of the knives are in arallel relation, this adjustment being e acted by loosening the nut 13 and manipulating the screw .8, the swivel plate or member being again locked in its readjusting position by tightening of the nut 13. When it is necessary to readjust the angular position of the swivel plate or member 6 to restore theknives to parallel relation, the graduated bar or member 20 is. correspondingly adj'usted in" its channel by manipulation of the screws 36 and 37 in order that the apertures 21 in this bar may occupy a proper graduated relation to the operative edges of the knives, and these screws .36 and 37 may also be adjusted to compensate for wearing away of the knives independently of the angular adjustment afforded by the swivel plate or member. These adjustments therefore enable'the graduated setting means to maintain a proper relation to the knives at all times.
